XRAY - Model racing cars

Hi,

I know a lot of drivers have been running Alexander Hagbergs rear modification on asphalt, narrowing the rear track of the car. I was wondering have many people tested this on carpet and if they think it would be better than the kit setting? Also how will this setting affect the cars handling on carpet?

I added it originally to help me on medium asphalt and left it on through laziness.
I don't seem to recall it making a huge difference on carpet so I left it.

The narrower rear end will give more rotation. The car will be less stable but carry more cornerspeed. I use it for both carpet and asphalt.
